Title: COMPACT HYDRAULIC SHOVEL
Abstract:
Provided is a compact hydraulic shovel configured so that: even if the hydraulic shovel is provided with a rotating body which is formed so that at least the rear end thereof will rotate within the vehicle width and which, therefore, has a limited equipment installation space, an accumulator can be installed on the rotating body; and the accumulator can be protected from external force occurring during work. The present invention relates to a small tail swing radius-type mini-shovel provided with an accumulator 30 for accumulating and recovering potential and hydraulic energy used by the drive of at least one of a traveling body 1, a rotating body 2, the rear end of which is adapted to rotate within the width of the traveling body 1, and a working device 3. The mini-shovel is configured such that: the accumulator 30 is located between a valve block 26 and a front longitudinal plate 41 of a longitudinal plate member included in a main frame 10 and is disposed along the front longitudinal plate 41; and piping connected to the accumulator 30 and the valve block 26 is disposed near the accumulator 30 and the valve block 26.
